6 Different Ways to Properly Insulate Your Steel Building

When it comes to steel buildings, insulation is a must. As the name suggests, insulation is the process of trapping heat in your steel building. This is important because it helps keep your building warm in the winter and cool in the summer, saving you money on your energy bills.

There are a few different ways to insulate your steel building, and the best option for you will depend on your specific needs and budget. Let’s take a closer look at each one.

1. Spray Foam Insulation

Spray foam insulation is a newer type of insulation that’s becoming more popular for steel buildings. It is made from a mix of chemicals that are sprayed onto the surface of the building, where they expand and harden into solid foam. Spray foam insulation can be either closed-cell or open-cell and can be used on both walls and ceilings.

2. Fibreglass Batts or Rolls

Fibreglass batts or rolls are the most common type of insulation for steel buildings. They’re made from glass fibres spun into a mat, then covered with a paper or foil backing. Fibreglass batts come in different widths and thicknesses to fit a variety of applications and can be installed either horizontally or vertically.

They are a cheaper alternative to spray foam insulation and can be just as effective if installed properly. However, they are more difficult to install and don’t provide as tight of a seal.

3. Radiant Barrier

A radiant barrier is a type of insulation specifically designed to reflect heat. It’s usually made from a reflective material like aluminum foil and can be installed on both walls and ceilings. A radiant barrier is most effective in hot climates and can help keep your building cooler in the summer.

4. Polyurethane Insulation

Polyurethane insulation is made from two liquids mixed together and then sprayed onto the building’s surface. Polyurethane insulation is available in both low- and high-density versions, so you can choose the level of insulation that’s right for your needs. It’s also resistant to mould and mildew, making it a good choice for humid climates.

5. Reflective Insulation

Reflective insulation is made from various materials, including aluminum foil, paper, and plastic film. It’s available in various thicknesses, so you can choose the level of insulation that’s right for your needs. Reflective insulation works by reflecting heat away from the building, so it’s a good choice for hot climates.

6. Cellulose Insulation

Cellulose insulation is made from recycled paper products and is a great way to insulate your home. This type of insulation is environmentally friendly and can help you save money on your energy bills. Cellulose insulation is also fire-resistant and can help to protect your home in the event of a fire.

Which Type of Insulation is Right for My Steel Building?

The type of insulation you choose for your steel building will depend on a number of factors, including the climate you live in, the type of building you have, and your budget. 

In general, fibreglass batts or rolls are the most affordable option, while spray foam insulation is the most effective. A radiant barrier is a good choice if you live in a hot climate, but it can be more expensive than other types of insulation.


There are many ways to insulate your steel building. Some of the most popular methods include spray foam insulation, fibreglass insulation, radiant barrier, polyurethane insulation, reflective insulation, and cellulose insulation. 

Each of these methods has its own set of benefits and drawbacks. Ultimately, the best insulation for your steel building will depend on your specific needs, preferences and budget.
